This module turns the standard Odoo eCommerce shop into a **read-only product
catalog**: visitors can browse, search and open product pages, but the standard
``website_sale`` shopping cart is not reachable any more.

It is meant for sites where the actual ordering happens somewhere else — for
example the group order flow of ``website_sale_aplicoop`` (``/eskaera``), a
quotation request form, or an offline/phone process — while the public shop is
still useful as a catalog.

What it does:

* Hides the cart link and badge from all 12 standard website header styles
  (default, mobile, hamburger, stretch, vertical, search, boxed, sidebar and
  sales one to four).
* Removes the "Add to cart" quick-add area from the product listing cards.
* Neutralizes the standard cart endpoints:

  * ``/shop/cart`` and ``/shop/cart/update`` redirect to a configurable URL.
  * ``/shop/cart/update_json`` returns an empty payload (no cart is written).
  * ``/shop/cart/quantity`` always returns ``0``.
  * ``/shop/cart/clear`` does nothing.

The redirect target is configurable, so the module stays generic: point it to
``/shop`` (default) to keep visitors in the catalog, or to whatever route
implements the real ordering flow of your site.
